CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of co-pending U.S.patent application Ser. No. 11/348,618, filed on Feb. 7, 2006. The priorapplication is hereby incorporated into the present application byreference.

The present invention relates generally to the communication of datapursuant to a high-speed data radio communication service, such as anEnhanced Data for GSM Evolution (EDGE) communication service. Moreparticularly, the present invention relates to a method, and anassociated apparatus, by which to allocate and to provide forcommunication of the data at reduced levels of latency. Communicationresources are allocated to provide for communication of data of a radioblock over multiple carriers and within a reduced time period, e.g.,within a single time frame.

BACKGROUND OF THE INVENTION

Data communication systems are used by which to communicate data andtheir use is pervasive in modern society. The capability of a datacommunication system is sometimes defined in terms of its throughputcapability due to the significance of the throughput rate at which datais communicated to the performance of a data communication service.High-speed data communication services have historically been performedby way of wireline communication systems. However, the evolution ofcommunication technologies increasingly permits high-speed datacommunication services to be carried out by way of radio, i.e.,wireless, communication systems. Increasingly, data services thatnecessitate the communication of large amounts of data in short periodsof time are able to be performed by way of a radio communication systemthat provides for the communication of the data at high data throughputrates. With increasingly data intensive communication services, there isa continuing need to provide for radio communication systems thatprovide for yet higher data throughput rates.

A cellular communication system is exemplary of a radio communicationsystem that increasingly is used by which to communicate data at highdata throughput rates. A GSM (Global System for Mobile communications)cellular communication system, for instance, has been developed andwidely deployed that provides for the performance of data communicationservices. Many GSM systems provide for GPRS (General Packet RadioService), a high-speed data communication service. An extension to GPRS,referred to as EDGE (Enhanced Data for GSM Evolution), is presentlyundergoing deployment. EDGE communications, in general, adds 8-PSKmodulation, incremental redundancy, and adaptive modulation and codingto GPRS communications. And, through these additions, an EDGE-capablecommunication system provides for communication of data at datathroughput rates that are significantly higher than those achievable inGSM/GPRS only communication systems. In spite of improved communicationcapabilities of an EDGE-capable system, there are ongoing efforts yetfurther to improve the communication capabilities of communications insuch a system.

In the existing EDGE communication scheme, a relatively hightransmission latency limits communication capabilities. The transmissionlatency results as, in the existing scheme, data of a radio block istransmitted over multiple TDMA (Time Division Multiple Access) frames ofa slotted interface defined in the communication scheme. Moreparticularly, the data of a radio block is transmitted in four burstsoccurring over four TDMA frames. And, as a result, to communicate thedata of the radio block requires the time period for responding to thefour frames in which to communicate the data of the radio block. Whenthe data is communicated pursuant to an acknowledgment scheme,additional time is required in which to acknowledge the reception of thecommunicated data.

If a manner could be provided by which to reduce the transmissionlatency of the existing communication scheme, improved effective datathroughput rates and improved communication performance would result.

It is in light of this background information related to communicationof data in a slotted-interface radio communication system that thesignificant improvements of the present invention have evolved.

DETAILED DESCRIPTION

The present invention, accordingly, advantageously provides a method,and an associated apparatus, for use in the communication of high-speeddata to perform a high-speed data radio communication service, such asin the communication of EDGE (Enhanced Data for GSM Evolution) datacommunicated during operation of an EDGE-capable communication system.

Through operation of an embodiment of the present invention,communication resource allocations are made to provide for thecommunication of data at reduced levels of latency. Communicationresources are allocated to provide for communication of data of a radioblock over multiple carriers within a reduced time period, e.g., asingle time frame.

By reducing the latency of the communication of the data, improvedeffective data throughput rates are achievable. Improved communicationperformance is provided as the reduced latency permits data needed toeffectuate a communication service to be communicated within a smallertime period.

Communication resources are allocated to communicate the data of a radioblock. While, conventionally, communication resources are allocated upona single carrier over a time period of four time frames, thecommunication resources allocated pursuant to operation of an embodimentof the present invention are allocated within a single time frame,across a plurality of radio carriers. Thereby, the data of an entireradio block is communicated within a single time frame, rather than thefour time frames over which the resources are conventionally allocatedand during which the data of the radio block is conventionallycommunicated.

In one aspect of the present invention, a determination is made of howmany, and which, radio carriers are available upon which to allocatecommunication resources. The determination is made, for instance, makinguse of knowledge of the communication capabilities of the communicationstations that are to be parties to a communication session. Theknowledge of the communication capability of a remote station, e.g., amobile station, is provided by a message sent by the mobile station tothe network infrastructure to inform the network infrastructure of thecommunication capability of the mobile station. And, responsive toreceipt of the message, allocations are available upon, or limited to,the radio carriers across which the mobile station is capable ofreceiving, or transmitting, data.

In another aspect of the present invention, communication resources areallocated both for downlink and uplink communications. Communicationresource allocations made at the network infrastructure for uplinkcommunications are communicated to the mobile station for subsequent useby the mobile station for the uplink communications. And, communicationresource allocations made for the downlink communications are alsocommunicated to the mobile station to alert the mobile station of theallocations to permit its operation best to detect and operate upon thedata, when communicated.

In another aspect of the present invention, communication resources areassigned and data communications are scheduled at a radio resourcecontrol logic layer of the communication system. The communicationresource assignments are made responsive to the communicationcapabilities of the communication stations that are to be involved inthe communication of the data and other criteria, such as theavailability of communication resources on the radio carriers otherwiseavailable for communications by the communication stations. And, whenthe resource allocations are assigned, the data scheduler schedules thecommunication of the data to effectuate its communication to effectuatethe communication service. When the communication stations are formed ofa plurality of RF transceiver front ends, each operable over a selectedradio carrier, control signals are generated at the radio resourcecontrol logic layer and provided to the transceiver front ends to causetheir operation in conformity with the assigned resources. And, when acommunication station is formed of a wideband RF transceiver front end,control signals generated at the radio resource control layer controlits operation.

Communication resource allocations are made subject to variousconstraints, including, e.g., time slots that are allocable, theavailable RF carriers, time requirements required of the communicationstations to tune to different carriers, as well as other criteria.

In general, an embodiment of the present invention is implementable inany of various radio communication systems that provide for multipleradio frequency channels using a time slotted protocol for datainterchange. A remote communication station operates to receive anddecode information communicated thereto on two or more radio frequenciessimultaneously. The transmission of the data is controlled through theassignment of communication resources and scheduling of datacommunications in conformity with the resource assignations.

Data conventionally is communicated over a number of frames thatconstitute a radio block. This amount of data, through operation of anembodiment of the present invention, is instead communicated within aselected number of time slots of a single time frame. The selectednumber of time slots corresponds to the number of frames thatconstitutes a conventionally-defined radio block.

In a further aspect of the present invention, a communication stationthat receives data communicated thereto upon the time slots allocatedwithin a single time frame acknowledges receipt pursuant to anacknowledgment scheme, either a positive acknowledgment or a negativeacknowledgment communication scheme. In a positive acknowledgmentscheme, the acknowledgments are communicated back to a sendingcommunication station within the same time frame as the time frame inwhich the data is communicated to the receiving station.

In these and other aspects, therefore, a method, and an associatedapparatus, is provided for facilitating communication of data by a firstcommunication station. The first communication station is operablepursuant to a communication scheme that provides for mobile allocationindex offset. The data is of an amount corresponding to datacommunicable during a selected number of time slots of a radio blockformed across a plurality of time frames. An assignor is adapted toreceive an indication of the amount of data to be communicated by thefirst communication station. The assignor is configured to assigncommunication resources defined in terms of mobile allocation indexoffsets across a plurality of radio carriers. A data scheduler isadapted to receive an indication of the communication resources assignedby the assignor. The data scheduler is configured to schedulecommunication of the data in conformity with the assignations made bythe assignor. The schedule of the communication of the data is made bythe scheduler providing for completion of the communication of the datawithin a single time frame of the plurality of time frames.

With these and other aspects in mind, reference is first made to FIG. 1.FIG. 1 illustrates a communication system, shown generally at 10, inwhich an embodiment of the present invention is operable. In theexemplary implementation, the communication system 10 forms a data radiocommunication system that operates in general conformity with theoperating protocols of a GSM/GPRS/EDGE (Global System for Mobilecommunications/General Packet Radio Service/Enhanced Data for GSMEvolution) communication scheme. The communication system, however, isanalogously also representative of other slotted-interface communicationsystems. While the following description shall describe thecommunication system in terms of its exemplary implementation, theteachings of the present invention are analogously applicable forimplementation in other types of communication systems, operablepursuant to other operating protocols.

The communication system 10 includes communication stations 12 and 14.The communication station 12 is representative of a network station. Thenetwork station is formed of elements of a network part of thecommunication system, and the communication station shall, at times, bereferred to herein as a network station. The communication station 14 isrepresentative of a mobile station, and the communication station 14shall, at times, be referred to herein as a mobile station 14.

A communication station 14′ is also shown in FIG. 1. The communicationstation 14′ represents another mobile station that is capable ofcommunicating with the network station 12. Separate point-to-pointcommunication sessions, as well as multicast communications, arepossible between the network station 12 and the communication stations14 and 14′. And, the communication system defines a multiple accesscommunication system.

Any of the communication stations 12 and 14 are capable of generatingand communicating EDGE data pursuant to performance of an EDGE dataservice. Exemplary operation of the communication system shall bedescribed with respect to downlink communication of data, i.e., dataoriginated at the network station and communicated to the mobilestation. Operation of the communication system in an uplink direction,i.e., from the mobile station to the network station is analogous.

The EDGE/GPRS/GSM operating protocols include definitions of an EDGEchannel structure. The EDGE channel structure defines a slottedinterface pursuant to a TDMA (Time Division Multiple Access) scheme inwhich groups of eight time slots forms a frame. And, a radio block isdefined as a group of four frames. Each frame is of a 4.615 ms timelength, and each time slot of the frame is one-eighth of such length or577 ms. As a radio block is formed of four time frames, the time lengthof a radio block is 4 times 4.615 ms or 18.46 ms. When communicationresources are allocated for the communication of data of a radio block,conventionally, at least 18.46 ms are required to communicate the data.This defines the transmission latency of EDGE communications. Furtherlatency exists if the receiving station transmits an acknowledgment,such as pursuant to an uplink state flag (USF) mechanism also set forthin the aforementioned protocols. The acknowledgment is returned in thenext TDMA frame following the reception of the full radio block. When anacknowledgment is utilized, five TDMA frames, or 20.824 ms time lengthscorresponding to five TDMA frames of 4.615 ms time lengths need to becompleted. An entire cycle requires nine, four plus four plus four plusone, time frames, or 41.435 ms time length extending between thebeginning of the reception of a block of data to the end of transmissionof a radio block to the end of transmission of an acknowledgment block.As the transmission latency is relatively lengthy, the latency forms aconstraint on the communication performance of a conventionalEDGE-capable communication system.

The communication stations 12 and 14 are functionally represented inFIG. 1. The communication stations are formed of functional elementsthat are implementable in any desired manner. Also, the functionsperformed by the various functional elements are not necessarilypositioned together at a single physical entity, but, instead, can bedistributed across two or more physical entities. For example, theelements shown to form portions of the network station 12 need not bepositioned at a single network entity, but rather can be distributedacross more than one entity, such as, for instance, across a basestation controller and a base transceiver station of the network.

The transmit chain portion of the network station 12 is shown in FIG. 1.The network station includes a radio protocol stack 18 to which userapplication data is applied by way of the line 22. The application datais for communication to one or more mobile stations 14 pursuant to oneor more EDGE communication sessions. The radio protocol stack includesvarious logical layers including a radio resource management (RRM)layer. Data is provided by the radio protocol stack to a basebandelement 24 by way of the lines 26. The baseband element performs variousbaseband operations including baseband processing, modulation, andchannel coding.

The network station also includes a radio element 28 formed of aplurality of radio frequency transceiver front ends (RF1-RFN) 30 towhich the data, once operated upon by the baseband element, is providedby way of the lines 32. The network station includes N RF transceiverfront ends 28. Each of the transceiver front ends is coupled to anantenna transducer 36 that operates to transduce data intoelectromagnetic form for communication by way of the slotted radio airinterface to the one or more mobile stations 14. That is to say, thenetwork station is capable of communicating on N carriers, such aspursuant to a mobile allocation index offset (MAIO) scheme. The mobilestation 14, e.g., is similarly configured and operable.

The network station 12 also includes a multi-carrier radio resourcecontrol logic element 42 of an embodiment of the present invention. Thelogic element 42 is functionally coupled to the radio protocol stack 18,here by way of the lines 43, 45, and 47, to the baseband element 24 byway of the lines 48, and to the transceiver front ends 28 of the radioelement by way of the lines 52. The logic element performs variousfunctions and, in the exemplary implementation, is embodied at the radioresource management logical layer.

The logic element 42 includes an assignor 54, a data scheduler 56, and amessage generator 62. The functions performed by the parts of the logicelement 42 are carried out in any desired manner, such as, for example,by algorithms executable by processing circuitry.

The assignor receives indications of the data that is to be communicatedpursuant to performance of a communication service during acommunication session, e.g., here, downlink data to be communicated bythe network station to one or more mobile stations. The indication ofthe characteristic includes, for instance, the amount of data that is tobe communicated or other indication that facilitates assignment by theassignor of the channel resource allocations or assignments. Channelresource assignments made by the assignor are provided to the datascheduler 56. The data scheduler operates to schedule datacommunications in conformity with the assignments made by the assignor.Appropriate control signals are provided to the RF transceiver frontends 30 and to the baseband element to control their respectiveoperation to provide for the communication of the data scheduled by thedata scheduler. Data scheduling information is here also provided to thedata scheduler by the radio protocol stack 18. The message generator 62is also provided with indications of the communication resourceassignments and data schedule made by the data scheduler. The messagegenerator operates to generate a message for communication to the mobilestation to alert the mobile station of the resource assignations andschedule made by the data scheduler. The message is here provided by wayof the line 43 to the radio protocol stack, subsequently to be operatedupon by the baseband element and caused to be communicated by one ormore of the transceiver front ends 30.

The receive chain portion of the mobile station 14 is illustrated in thefigure. The mobile station includes antenna transducers 64, an RFelement 66 formed of RF transceiver front ends 67, a baseband element68, and a radio protocol stack 74.

The mobile station includes a multi-carrier radio resource control logicelement 78, also of an embodiment of the present invention. The element78 includes a detector 82 and a controller 84. The radio resourcecontrol logic element is coupled, at least functionally, to the radioprotocol stack, here indicated by way of the lines 86 and 88, to thebaseband element by way of the line 92, and to the RF transceiver frontends of the RF element by way of the lines 94.

The detector 82 operates to detect a message generated by the messagegenerator 62 of the network station and communicated to the mobilestation. And, the detector operates to extract values contained in themessage or otherwise operates to identify the channel assignations ordata schedule contained in the communicated message. Detections made bythe detector are provided to the controller 84. The controller operatesto control operation of the mobile station responsive to the valuesdetected in the message. For downlink communications, the controllercauses operation of the mobile station in a manner best to receive thesubsequently communicated EDGE data. And, for uplink communications, thecontroller causes operation of the mobile station to communicate bestuplink data that is subsequently communicated by the mobile station.

FIG. 2 illustrates a communication system, similar to that shown in FIG.1, also formed of a set of communication stations 12 and 14. Elements ofthe communication system 10 shown in FIG. 2 that correspond to thoseforming the communication system shown in FIG. 1 arecommonly-referenced. The function, operation, and connection of suchcommonly-referenced elements correspond with their counterparts shown inFIG. 1. Reference to the description of FIG. 1 provides the details oftheir function, operation, and connection.

Here, in contrast to the communication stations 12 and 14 shown in FIG.1, the communication stations include wideband RF transceiver front ends98 and 106. That is to say, the network station includes a single radiofrequency transmitter 98 that transmits multiple, contiguous radiofrequency channels converted from a single baseband signal. And, themobile station 14 includes a single radio frequency receiver 106 havinga radio frequency and baseband bandwidth sufficiently wide to receivemore than one contiguous radio frequency channel and associated basebandinformation.

During operation of the multi-carrier radio resource control logicelement 42, communication resource allocations are made to minimize thenumber of burst periods assigned over all radio frequency carriers toboth downlink and uplink time slots, as appropriate, subject to variousconstraints. First, the time slots must be allocable; that is, the timeslots are not used for other traffic communications by other sets ofcommunication stations pursuant to other communication sessions.

Second, the time slots that are allocated are allocated over the sum ofall allocable burst periods and the sum of all available mobile-station,radio frequency receiver elements is greater than or equal to the numberof burst data that are required for the transmission of one radio block.

Third, the time slots are allocated over the sum of all allocable burstperiods and the sum of all available mobile station radio frequencyreceivers MOD the number of burst data that are required fortransmission of one radio block is equal to zero. That is to say, onlyfull blocks are allocated, not partial radio blocks.

Fourth, assignments are further dependent upon the minimum latencyrequired to tune the RF stage, either the plurality of transceiver frontend elements or the wideband transceivers and become ready either toreceive on another carrier frequency or transmit is observed.

Fifth, the resource assignations and data schedule is further dependentupon the minimum latency period required to tune the RF stage, howsoeverimplemented, and become ready to receive on a measurement frequency.And, sixth, a final constraint is that a measurement frequency is notequal to a transmit frequency.

The above decisions and constraints are represented mathematically by:

${{MIN}\text{:}\mspace{14mu}{\sum\limits_{b = 1}^{Nb}\;{B_{b}u_{b}}}};{u \in \left\{ {0,1} \right\}}$${{ST}:u} = \begin{Bmatrix}{a = {{1\bigwedge\left\lbrack {{\left( {{\sum\limits_{b = 1}^{Nb}\;{\sum\limits_{R = 1}^{N_{R}}\; T_{bR}}} \geq d} \right)\bigwedge\left( {{\sum\limits_{b = 1}^{Nb}\;{\sum\limits_{R = 1}^{N_{R}}\;{T_{bR}{MOD}\mspace{11mu} d}}} = 0} \right)\bigwedge L_{T}} \geq {B\bigwedge L_{M}} \geq {B\bigwedge f_{m}} \neq f_{t}} \right\rbrack}:1}} \\{{Else}:0}\end{Bmatrix}$Where:

-   b=burst period-   R=RF deck number (both transmit and receive)-   Nb=Maximum burst periods possible in allocation-   Nr=Maximum number of RF decks available for simultaneous reception    in mobile terminal-   B_(b)=Burst period (for GSM/EDGE=577 μs) at timeslot number “b”-   T_(bR)=Radio resource of timeslot at timeslot number “b” on RF deck    “R” for mobile receiver-   u_(b)=Utilization of timeslot “b” according to constraints (Boolean)-   a=Timeslot availability for allocation to mobile downlink (Boolean)-   d=Number of data bursts required per radio block (for GSM/EDGE=4)-   L_(T)=Minimum latency required to switch between last allocated    receive slot and either i) another allocated receive slot on another    RF carrier or ii) the allocated transmit slot (for GSM/EDGE=1 burst    period=577 μs)-   L_(M)=Minimum latency required to switch between last allocated    transmit slot and measurement slot (for GSM/EDGE=1 burst period=577    μs)

FIG. 3 illustrates a representation, shown generally at 112, ofexemplary resource allocations made pursuant to operation of anembodiment of the present invention. Here, resources are allocated upontwo radio carriers 114 and 116. Four time frames, each formed of eighttime slots on each of the two radio carriers is shown in the figure.Time slot assignations are made on the first and second time slots ofboth of the radio carriers 114 and 116. That is to say, during the timeperiod corresponding to a single time frame, four time slots areallocated for communication of data. The four time slots provide for thecommunication of data of an amount corresponding to the data that isconventionally communicated over a radio block defined over four timeframes. The blocks 122 are representative of the downlink data blockcorresponding to the time slots allocated on the separate carriers 114and 116.

In the exemplary representation, acknowledgments are further returnedacknowledging receipt of the data communicated upon the allocated timeslots. The time slots 124, within a single time frame, represent timeslots within which the exemplary uplink acknowledgments are returned tothe network station.

Thereby, within the time period corresponding to a single time frame,data constituting the data of an entire radio block is communicated tothe mobile station, and the mobile station acknowledges receipt of thedata. The coding of an entire block in an acknowledgment of itsreception and decoding, within a single TDMA frame period, is therebyprovided.

Further represented in the figure is an exemplary resource allocation ofa radio block in conventional practice, indicated at 126. Inconventional operation, a single time slot is allocated within a singletime frame, and time slots over four time frames are allocated upon asingle radio carrier. And, when acknowledgments are provided, theacknowledgments are provided in subsequent time frames. Comparison ofthe allocations indicates the reduced latency provided through operationof an embodiment of the present invention.

FIG. 4 illustrates another representation, shown generally at 132, hereof a two-receiver mobile station and resource allocations over threetime frame periods, each time frame period formed of eight time slots,numbered 0-7 in FIG. 4. As indicated by the circles 134 and 136, theresources allocated during the first two time slots of the RF channelcarriers 1 and 2 satisfy the constraint indicated mathematically in thecircle 136. Subsequent transmit allocations in time slots identified astime slots 3, 4, 5, and 6 are allocated with the latency constraintindicated by the circles 138 and 142. The additional constraints areindicated by the circles 146 and 148, 152 and 154, and 156.

Again, analysis of the resource allocations indicate that the datacorresponding to an entire radio block is communicated, andacknowledged, within a single time frame. Additional exemplaryallocations are indicated in the second and third time frames of theillustration of FIG. 4.

FIG. 5 illustrates a method flow diagram, shown generally at 162,representative of the method of operation of an embodiment of thepresent invention. The method facilitates communication of data by afirst communication station pursuant to a communication scheme thatprovides for mobile allocation index offset. The data is of an amountcorresponding to the data communicable during a selected number of timeslots of a radio block formed across a plurality of time frames.

First, and as indicated by the block 166, communication resources areassigned. The communication resources that are assigned are assignedacross a plurality of radio carriers.

Then, and as indicated by the block 168, communication of the data isscheduled in conformity with the assignations made during the operationof assignment. The schedule of the communication of the data providesfor completion of the communication of the data within a single timeframe of the plurality of time frames. Subsequently, and as indicated bythe block 172, a message is generated. The message includes valuesrepresentative of the schedule. The message, when communicated,identifies the schedule to a remote station. And, as indicated by theblock 176, the message is communicated to the remote station. And, asindicated by the block 182, an acknowledgment is returned by the remotestation to acknowledge receipt of data subsequently communicated inconformity with the schedule.

As the resources are assigned, the data is scheduled for communication,and is communicated, with lessened levels of latency, improvedcommunication performance is provided.
